I used the frequencies of different learning strategies that students mentioned in a 2x2 factorial within design (across 4 different situations) to draw up several plots in R. What I tried to find out was if there is a lot of overlapping variance in two or more strategy types, or if there is one strategy type almost explaining no variance in my data. But now, I do not really know how to comprehensively interpret my plots. I only understand the screeplot and think that the clusplot suggest a 5 factor solution and the cluster plot a three factor solution. Can someone help out?
